Welcome to the NCSC Ireland website

The National Cyber Security Centre (NCSC)

The National Cyber Security Centre (NCSC) was founded in 2011 and is an operational arm of the Department of Communications, Climate Action and Environment (DCCAE). The NCSC is
responsible for advising and informing Government IT and Critical National Infrastructure providers of current threats and vulnerabilities associated with network information security.

The main roles of the NCSC are to lead in the management of major cyber security incidents across government, provide guidance and advice to citizens and businesses on major
cyber security incidents, and develop strong international relationships in the global cyber security community for the purposes of information sharing. In the period since
2011, the unit has focused its efforts on building capacity and establishing a stable base for its operational work.

The NCSC encompasses the State’s National/Governmental Computer Security Incident Response Team (CSIRT-IE). CSIRT-IE is an internationally accredited response team with its
main function being the enhancement of situational awareness for constituents and for the provision of incident response for national cyber security incidents. CSIRT-IE has initially focused on the
State sector and acts as a national point of contact for all cyber security matters concerning Ireland.
